The build of the PrintrBot Simple Metal 3D printer continues! In this second episode, Will and Norm wade through photo-instructions for this low-cost 3D printer, working up from the build platform to the Z-axis and plastic extruder. Along the way, we explain the purpose of each component. Follow along in our 3D printer building adventure! (This video was brought to you by Premium memberships on Tested.
